Application filed March 25, 1914. Serial No. 827,182.

To all whom it may concern:

Be it known that I, DAVID S. HOWELL, a citizen of the United States, residing at Oconto, R. D. No. 1, in the county of Oconto shaped clamps which terminate at their lower ends in threaded bolt portions 6. These clamps 5 are positioned upon the rack 3 so as to allow the clamps to extend over and State of Wisconsin, have invented certhe sides of the wagon body 1. Upon each so tain new and useful Improvements in Hayclamp 5 there is positioned a plate which Rack Locks, of which the following is a comprises a body portion 7 which is pro' specification, reference being had therein to vided with the downwardly extending lugs the accompanying drawing. 8 having the openings 9 formed therein.

10 This invention relates to a hay rack lock The laterally extending cars 10 are formed 65 and the principal object of the same is the upon the upper outer sides of the lugs so production of a lock for detachably retainas to form the shoulders 11. This body 7 is ing a hay rack or similar article upon the elongated so as to fit upon the lower porbody of the wagon for preventing the accitions of the rack 3 whereby the ears 10 will dental removal therefrom, when in use. embrace the rack so as to allow the shoulders '70 Another object of this invention is the 11 to prevent the lateral movement of the production of a lock which is adapted to be plate upon the rack. These ears 10 are prosupported upon the hay rack in such a manvided with apertures 12 through which the. nor as to allow the hay rack to be efficiently threaded bolt ends 6 of the clamp 5 are 20. looked upon the upper portion of a wagon adapted to pass so as to allow the threaded 75 body, this lock being capable of releasement ends 6 to extend for a distance below the when it is desired to remove the hay rack cars 10 for allowing the nuts 13 to be from the wagon body. threaded thereon, whereby the plate will be WVith these and other objects in View this held securely upon the rack without danger invention consists of certain novel combinaof the same becoming accidentally loose. 80 tions, constructions, and arrangements of The plate 7 is also providedat its rear end parts as will be hereinafter fully described with an aperture 1d for the reception of any and claimed. suitable securing means which is adapted to In the accompanying drawings :Figure pass into or engage the rack 3 upon which 1 is a fragmentary side elevation of a porthe plate is supported for efficiently holding 85, tion of a wagon body and hay rack showthe rear portion of the plate in position. ing the locking device in operation.

It will, of course, be by numerals 1 designates an ordinary wagon observed that the lower threaded bolt ends 7 body upon which the usual hay rack is 6 of each clamp 5 are offset relative to the loo adapted to be supported. The hay rack 3 body of the clamp as clearly disclosed in is adapted to be positioned upon the wagon Fig. 1 for allowing the lower ends of the body 1 so as to allow the locking members clamp to pass through the apertures 12 to engage the keepers carried by the wagon formed in the ears 10 without having bindbody 1 whereby the rack will be efficiently ing action, owing to the fact that the ears 10.5 supported upon the wagon body without 10 are formed at a distance from the side danger of the same falling or being jarred edges of the plate 17. from position. The clasps which are adapted to detach- For the purpose of supporting the locks ably retain the rack upon the wagon body upon the hay rack there are provided U- are all formed similar, each one comprising a body 17 having a vertical slot 18 formed therein. A neck 20 is formed integral upon the upper portion of the body 17 of each clasp and is provided with central bore 21 having the secondary slot 21 communicating therewith. The bearing sleeve havin central bore 28 is positioned between the lugs 8 so as to allow the pivot pin to pass through the openings 9 formed in the lugs 8 and through the bore 23 formed in the bearing sleeve 22 whereby the clasp will be held in pivotal engagement with the plate. The plunger is positioned within the central bore 21 of the neck 20 so as to freely reciprocate therein and upon the inner end of the plunger the coiled spring is adapted to bear, as disclosed in Fig. 2. This coiled spring 25 is also positioned within the bore 21 so as to bear at its inner end upon the inner end portion or the neck 20 formed adjacent the bore 21". For the purpose of allowing the plunger 2 to be moved into the interior of the bore 21 there is provided a pin 26 which extends through the slot 21 so as to engage the plunger thereby allowing the plunger to be moved into the interior of the neck by compressing the spring when it is so desired. When this plunger 2 1 is in an extended position the outer end thereof will extend into the slot 18 as clearly disclosed in Fig. 2. The outward movement, however, of this plunger is limited by the pin 26 since the pin will engage the neck 20 adjacent the outer end of the slot 21. A keeper 27 is formed integral on the plate 28, this plate being secured to the side of the wagon body 21 by means of the securing screws or bolts 29. This keeper is provided at its outer end with a beveled face 30 which extends toward its upper portion and upon which the plunger 24c is adapted to ride when the clasp is being moved to a locked position. The lower end of the body 17 of the clasp is provided with an outwar lly extending lip 31 for allowing the clasp to be easily gripped when it is desired to remove the same from engagement with the keeper 27. When this device is in use the rack is first placed upon the upper portion of the Wagon body. By swinging the clasp toward the keeper 27 the outer end of the keeper will pass through the slot 18 formed therein at which time the plunger 24- will ride upon the inclined face 30 thereby compressing the spring 25 within the bore 21. As soon as the plunger has passed over the inclined face 30 it will then be sprung outwardly so as to engage the inner pocket portion 82 of the keeper 27, thereby locking the clasp in engagement with the keeper. The clamp 5 engages the rack and supports the plate 7 upon the lower portion of the rack. The plate will hold the rack against lateral movement upon the wagon body since the lugs 8 and rib 15 formed at spaced distances from been each other will lit upon the side portions of the side boards of the wagon body as shown in Fig. 2. Since the keeper 2? passes through the slot 18 formed in the clasp any danger of the rack being arred or accidentally moved from the upper portion of the wagon body will be eliminated since the plunger will retain the clasp in engagement with the keeper. l/Vhen, however, it is desired to remove the rack from the upper portion of the wagon body 1 the pin 26 may be moved toward the inner end of the slot 21 formed in the neck 20 thereby causing the plunger 2% to compress the spring 25 and thus remove the plunger 2 1 from the pocket 32 ot the keeper 2'7. A this time the lip 31 may be gripped and the clasp swung upwardly thus unlocking the device and allowing the rack to be removed from the wagon body after all of the locking members have thus free from engagement with each keeper 27.

From the foregoing description it will be seen that a simple and elhcient device has been produced for efliciently retaining the rack upon a body, this means being elliciently supported upon the rack and being adapted to be easily operated for retainin or for releasing the rack from engagement with the Wagon body.
